Now the problem we are facing is that the non-renewable source of energy is depleting and solar energy is present in abundance but harnessing the solar power involves many problems regarding its efficiency. Photovoltaic method is also not that efficient as we need it to be so by simply combining one or two methods we can improve the efficiency of solar panels and can harness solar energy at a great level and use it to replace the coal and petroleum.
The device itself is light, compact and portable, but is capable of exerting great force. The device pushes liquid against a piston; pressure is built in the jack's container. The jack is based on Pascal's law that the pressure of a liquid in a container is the same at all points.
A hydraulic jack is a jack that uses a liquid to push against a piston. The principle states that pressure in a closed container is the same at all points. If there are two cylinders connected, applying force to the smaller cylinder will 8. Page 4 result in the same amount of pressure in the larger cylinder. However, since the larger cylinder has more area, the resulting force will be greater. In other words, an increase in area leads to an increase in force. The greater the difference in size between the two cylinders, the greater the increase in the force will be.
A hydraulic jack operates based on this two cylinder system. In the recent past there has been a significant increase in the use of hydraulics in our industries. The use of oil hydraulic systems as a means of power transmission in modern machines evolved a few decades earlier in the western world.
But its applications in Indian industries are of comparatively recent choice and hence, there is great deal of urgency and importance to master the art of its applications and maintenance. Hydraulic systems are not extensively use in machine tools, material handling devices, transport and other mobile equipment, in aviation systems, etc..
At the moment there exists a big gap between the availability and requirement of skilled man power in this vital field of the modern engineering in India. To bridge the gap, it is essential that our design and application engineers and maintenance personnel from the lowest to the highest level are given extensive on job training so that operational efficiency and effectiveness of machineries using a hydraulic system as the prime source of power transmission can be maintained at an optimum level.
Apart from the fluid power system designer, a good maintenance and millwright mechanic should also have first hand theoretical knowledge to enable him to tackle practical problems encountered during installation, operation and maintenance of the hydraulic equipment. A jack is a mechanical device used to lift heavy loads or apply great forces.
Jacks employ a screw thread or hydraulic cylinder to apply very high linear forces. A mechanical jack is a device which lifts heavy equipment. The most common form is a carjack, floor jack or garage jack which lifts vehicles so that maintenance can be performed. More powerful jacks use hydraulic power to provide more lift over greater distances. Mechanical jacks are usually rated for a maximum lifting capacity for example, 1.
Oil is usually used for the liquid because it is self-lubricating and has stability compared with 9. Page 5 other liquids. When the plunger comes up, it pulls the liquid through a check valve suction pump. When the plunger is lowered again, it sends liquid through another valve into a cylinder. A ball used for suction in the cylinder shuts the cylinder and pressure builds up in the cylinder.
The suction valve present in the jack opens at each draw of the plunger. The discharge valve, which is outside the jack, opens when oil is pushed into the cylinder. The pressure of the liquid enables the device to lift heavy loads.
The most common form is a car jack, floor jack or garage jack which lifts vehicles so that maintenance can be performed. Figure 1: Mechanical Jack Car jacks usually use Mechanical advantage to allow a human to lift a vehicle by manual force alone. The jack shown at the right is made for a modern vehicle and the notch fits into a hard point on a unibody.
Earlier versions have a platform to lift on the vehicles' frame or axle. Page 6 1. Use of jacks not designed for a specific vehicle requires more than the usual care in selecting ground conditions, the jacking point on the vehicle, and to ensure stability when the jack is extended. Hydraulic jacks are often used to lift elevators in low and medium rise buildings.
A hydraulic jack uses a fluid, which is incompressible, that is forced into a cylinder by a pump plunger. Oil is used since it is self-lubricating and stable.
When the plunger pulls back, it draws oil out of the reservoir through a suction check valve into the pump chamber. When the plunger moves forward, it pushes the oil through a discharge check valve into the cylinder.
The suction valve ball is within the chamber and opens with each draw of the plunger. The discharge valve ball is outside the chamber and opens when the oil is pushed into the cylinder. At this point the suction ball within the chamber is forced shut and oil pressure builds in the cylinder. In a bottle jack the piston is vertical and directly supports a bearing pad that contacts the object being lifted.
With a single action piston the lift is somewhat less than twice the collapsed height of the jack, making it suitable only for vehicles with a relatively high clearance.
For lifting structures such as houses the hydraulic interconnection of multiple vertical jacks through valves enables the even distribution of forces while enabling close control of the lift. This eliminates the need for the user to actuate the hydraulic mechanism, saving effort and potentially increasing speed.
Sometimes, such jacks are also able to be operated by the normal hydraulic actuation method, thereby retaining functionality, even if a source of compressed air is not available. Page 7 Figure 2: House Jack A house jack, also called a screw jack is a mechanical device primarily used to lift houses from their foundation. A series of jacks are used and then wood cribbing temporarily supports the structure.
This process is repeated until the desired height is reached. The house jack can be used for jacking carrying beams that have settled or for installing new structural beams.
This pad moves independently of the house jack so that it does not turn as the acme-threaded rod is turned up of plumb 1. For decades, there has been not a single report that proves its credibility in being the safest and most likely method for the lifting load construction. The hydraulic jack systems have now gained a lot of popularity.
The time and manpower needed for lifting the plates to the height is amputated. Construction work remains unaffected by snow or rain. These lenses are made of glass and used to magnify the object at distance by their converging and diverging traits.
Among these Bi-Convex lens is present which converses the light at a point and by converging the light it can intensified the rays for betterment. Our project is all about harnessing more energy from the sun, and in low-light regions. Presently Solar Panels are being used to store energy from sun but there are various problems which decreases the efficiency of power stored.
So to increase the efficiency of storage of solar energy, we have planned to develop a system which can generate more energy from sun and hence more power can be stored with minimum losses. Page 9 2 Chapter 2 2. It requires great effort to lift the car with a screw jack which usually comes with the car. We have devised a way for reducing the immense human effort required in changing a flat tyre of a car. Our project is all about making the life of common people easy.
In this we have increase the efficiency of solar panels by placing a Bi-convex lens which converses the sun rays and focuses it on the panel which will charge the battery much faster than usual. However it is hybrid vehicle which integrate both solar energy and hydraulic energy. This shall be achieved by sophisticated mechanical system and electric circuitry. The Greek who made the most lasting contribution to hydraulics was the Sicilian mathematician Archimedes B. This is the basis of hydrostatics and also of the apocryphal story that Archimedes made this discovery in his bath and forthwith ran UN clothed through the streets crying "Eureka!
Stevin Simon  the Dutch hydraulic engineer was the essential contribution to hydrostatics in , nearly two millennia after the time of Archimedes. Stevin showed that the force exerted by a liquid on the base of a vessel is equal to the weight of a liquid column extending from the base to the free surface. That this force does not depend on the shape of the vessel became known as the hydrostatic paradox.
Galileo  in his experiment thrown initial light on the problem of gravitational acceleration. In his study of the phenomenon, he noted that a body sliding freely down an inclined plane attained a certain speed after a certain vertical descent regardless of the slope; it is said that he hence advised an engineer that there was no point in eliminating river bends, as the resulting increase in slope would have no effect!
Whereas Leonardo was a loner, Galileo gathered a small school around him.
One of his students, the Abbe Benedetto Castelli , rediscovered the principle of continuity and delved further into other aspects of the science, though not always correctly. His younger colleague Evangelista Torricelli applied his mentor's Page 11 analysis of parabolic free-fall trajectories to the geometry of liquid jets. Torricelli also experimented with the liquid barometer, the vacuum above the liquid column being comparable to the void that Galileo found to develop in a pump whose suction pipe exceeded a certain length; in other words, nature abhorred a vacuum only up to a certain point.
Mariotte Edme  is often called the father of French hydraulics because of the breadth of his experimentation; this included such matters as wind and water pressure and the elasticity of the air, a quality which we usually associate with the name of the Englishman Robert Boyle whereas the latter appears to have coined the word hydraulics, in France Boyle's law bears the name of Mariotte.
Only a few years younger than Mariotte, the Italian Domenico Guglielmini is similarly considered by many to have been the founder of the Italian school.
But whereas Mariotte was a laboratory experimenter, Guglielmini made extensive field measurements of river flow. Interestingly enough, Guglielmini eventually became a professor of medicine. Pascal Blaise  in this research paper concerned himself with the same barometric problems as the equally short-lived Torricelli not to mention Mariotte , but it was Pascal who finally completed the principles of hydrostatics. Not only did he clarify the transmissibility of pressure from point to point and its application to the hydraulic jack, but he also showed that the barometric i.
Euler , in his research derived Bernoulli equation, from his equations of acceleration for the conditions of steady, ir-rotational flow under gravitational action.
Euler also deserved credit for a number of equations of hydraulics and for inventing at least on paper a workable hydraulic turbine. Worthy of mention in the same breath as Euler and the Bernoulli was Jean Lerond d'Alembert , best known for his coeditor ship of the French encyclopedia but also a mathematician in his own right.
He proved in that under steady, ir-rotational conditions a fluid should offer no resistance to the relative motion of an immersed body: D'Alembert is also known for having been one of three French scientists to have made in what were said to have been the first towing-tank tests of ship-model drag. They were, however, preceded by Page 12 some nine years by those of our own Benjamin Franklin 90 , himself a potential hydraulician.
German Gotthilf Ludwig Hagen  conducted in some very meticulous measurements of the flow of water in small-diameter tubes, utilizing the water temperature instead of the viscosity as one of the parameters. A few years later the French physician Jean Louis Poiseuille repeated the experiments independently using even liner tubes to simulate blood vessels, and oil and mercury in addition to water.
Except in Germany, the phenomenon is known as Poiseuille flow, even though neither Poiseuille nor Hagen really understood the mathematics of the phenomenon.
Hagen, however, had remarked in an paper that the flow was not always laminar, the efflux jet sometimes being clear and sometimes frosty; similarly, sawdust suspended in the water sometimes moved in straight lines and sometimes very irregularly; in the latter instances he noted that his resistance equation no longer applied.
Da Vinci Leonardo , in his research in the late s, first demonstrated the use of a screw jack for lifting loads. It is not until the late s that we have evidence of the product being developed further. Whitworth Joseph  in his research recognized the need for precision had become as important in industry as the provision of power.
Page 13 Henry Frank  in his experiment during the early s in Coati cook, designed a lifting jack.
The device was efficient, reliable and easy to operate. It was used in the construction of bridges, but mostly by the railroad industry, where it was able to lift locomotives and railway cars. The idea was based on the familiar lever and fulcrum principle and he needed someone to manufacture it. That person was Samuel Duff, proprietor of a local machine shop. Over the next 30 years the Duff Manufacturing Company became the largest manufacturer of lifting jacks in the world, developing many new types of jack for various applications including its own version of the ball bearing screw jack.
Norton to create the Duff-Norton Manufacturing Company. Both companies had offered manually operated screw jacks but the first new product manufactured under the joint venture was the air motor-operated power jack that appeared in With the aid of the relatively new portable compressor technology, users now could move and position loads without manual effort. The jack, used predominantly in the railway industry, incorporated an air motor manufactured by The Chicago Pneumatic Tool Company.
Page 14 Boris Alexandro itch Bakhmeteff  A Russian professor and consulting engineer, Bakhmeteff was sent to the United States as ambassador by Kerensky, after whose fall he formed, with a number of other White Russians, a profitable match factory and taught hydraulics part-time at Columbia University; he also published as an Engineering Societies Monograph an extended translation of his St. Petersburg dissertation on open-channel flow.
A native Hungarian, von Karmfin was one of Prandtl's earliest doctoral students and later a very productive professor at Aachen, Germany; with the rise of Hitler, he migrated to Cal Teeh at Pasadena, and then to Washington as air force consultant during the war; he was the first to receive from President Kennedy the new National Medal of Science, and his autobiography The Wind and Beyond not to mention the five volumes of his collected writings makes for absorbing reading.
Descartes Rene , the French scientist to whom we owe the Cartesian coordinate system, sought valiantly to reconcile the Aristotelian teachings that had been adopted by his church with the mechanics of the solar system. He thus hypothesized that the planets were carried in their orbits by a system of giant vortices endowed with a fixed "quantity of movement.
Newton even conducted a variety of experiments on the resistance due to fluid tenacity, elasticity, want of lubricity, and inertia encountered by bodies in motion to prove that nothing of the sort occurred in space. In the course of these studies, he formulated the speed of sound in air except for the adiabatic constant , the basis of viscous shear, and the equation of what we now call form drag except that he mistakenly considered shape itself to be of no importance.
He also invented what he termed the theory of fluxions, now known as the calculus. Duff-Norton , there was clearly potential for using this technology for other applications and only 10 years later, in , the first worm gear screw jack, that is instantly recognizable today, was offered by for adjusting the heights of truck loading platforms and mill tables.
With the ability to be used individually or linked mechanically Page 15 and driven by either air or electric motors or even manually, the first model had a lifting capacity of 10 tons with raises of 2 or 4. Ramachandra C G, Krishna Pavana , in his project said that main intention is to reduce the manual work and save time during the replacement of the failed tire. To validate our point to overcome the difficulties of the above said problems, an inbuilt jacks have been designed and fabricated which is assembled on the vehicle.
REMOTE CONTROLLED ELECTRICALLY OPERATED HYDRAULIC JACK
With the help of the existing brake pad and fluid arrangement of the braking system we incorporate the jack into to chassis of the vehicle with a set of unions, ball valves, master cylinder, five- way directional control valve, separated by a piping arrangements lifts the incorporated jack to action desired without raising any sweat of the driver. Author concludes that with no barrier, the flat plate collector is more capable than the spherical surface collector.
But due to continuing change of the sun location and only a shorter instance in a day that the flat plate collector can collect, efficiency is not as much. The reverse of the spherical surface can collect considerable amount of scattered radiation and reflected solar energy that makes it as efficient as the flat plate with no barrier.
Taking into account the barriers, the spherical surface collector can be enhanced choice in definite situations. Author eliminates the two main problems with parabolic solar concentrator which requires better field of view and good tracking system. The condition of two way tracking system for a parabolic type solar concentrator permits exact and effortless focus of solar radiation on the receiving surface of the utensil positioned at the focus of the reflector.
German based Scientist Andre Brosesel used a spherical glass to strengthen the Solar energy collection has becomes effective on immeasurable scales, particularly in solar farms, where panels adjust themselves optimally to collect the most light feasible. In comparison with old-fashioned PV dual-axis solar panels, the spherical lens includes a fully rotational, weather proof tracking system, which will work effectively on inclined surfaces and walls.
This could permit any building to be retrofitted with these glass lenses to produce more solar power. The spherical lens has the aptitude of concentrating scatter daylight and even moonlight, creating solar energy collection a more effective use.
The third model is filled with water and has many photovoltaic cells to produce solar energy. With additional expansion, and the declining cost of solar panels, such a new device might be uncommon, especially when comparing the size between it and other similar photovoltaic cells. However, its ability to generate energy more efficiently and the chances to even produce energy at night might become the deciding factors.
Page 17 4 Project Design and Implementation 4. The calculation for the energy storage due to the converging sunlight is required and it is very difficult to find the change in voltage with a time interval. Therefore in order to calculate these variables we had to resort to experimentation.
Once the actual model is built we needed to further calculate the various forces on the hydraulic jacks that we had used. This means comparing the theoretical values to the actual values. The main motive of the project is to compare the efficiency of solar panel with and without using Bi-convex lens and using this concept to fabricate a user friendly automatic jack system.
In this cad model, solar panel is placed on the roof of the car and lens is placed on the lens stand which receives the sun rays and concentrates them on the panel. Page 18 Figure 3: Side View Figure 4: Isometric View Page 19 5 Approach to design The project has been divided into two parts which has their own significance.
The first part is to basic concepts of optics which is used to increase the efficiency of solar panel. The second part is a user friendly system to lift the car at the time of tire puncture. The first part of the project deals with solar energy, solar panel, Bi-convex lens and basic electrical concepts. The Sun is the main energy source of the Earth.
All fossil fuels used today are indirect forms of solar energy. Most of the renewable energy sources, such as winds and ocean waves, also exist because of the sun. Therefore, collecting energy directly from the sun is an intuitive approach.
Solar energy is in most abundance in nature and is a renewable energy source. It is a nonpolluting source of energy and reduces greenhouse effect.
Working Principle of HYDRAULIC JACK or HYDRAULIC PRESS
Hydraulic cylinder, pumping rod, cam, DC motor, pressure relief valve, battery, switch guide for pumping rod to control unit. Our Indian road conditions are not comfort to ride the vehicles. In order to change the tyres, the drivers are met so many problems.
Because they have to lift the vehicle by using the manual jacks. In manual jack, they have to rotate the lever by applying their own manual power. Its very difficult to operate. Apart from this manual jack, now in automobiles hydraulic jack, pneumatic jack, etc. But now we had implementing a new concept in hydraulic jack through project.
In our project, the power jack operating through hydraulic system comprises of following components like pump, cylinder, handle, ram, with self locking nut. Our project is successfully implemented to lift the vehicles without any dangerous. It will reduce the burden of the workers as well as protect from the accident. This project will be very useful for lifting purpose of vehicles which are used in automobile field, especially in tire workshop.
The prime movers are operated by i electrical system ii Hydraulic system iii Pneumatic system. In electrical system, the rotary motion is provided by simple motors. The linear motions can be obtained by converting rotary motions with the aid of screw jack or Rack and pinion.
In Hydraulic system, enclosed water or oil can be used to convey energy from one location to another. In Greek, hydra means water. In Pneumatic system, enclosed gas normally compressed air is used to transfer energy from one location to another. In Greek, Pneumatic means wind. All liquids are non-compressible and can be used to transmit power any load to be lifted offers resistance to flow of liquid.
This resistance to flow is pressure. Nowadays, the vehicle places a vital role for transport. If May tyre gets punch red, the drivers are facing more difficulties to change the tyre or to lift the vehicle by using jack. They are using either manually operated jack or hydraulically operated jack.
Hydraulic jack takes less man power to lift. Even system failure may be slip occur locking nut protect from slip. Flag for inappropriate content. Related titles. Jump to Page. Search inside document.
